This inv nt n re ates o mpro emen in racks for use in ovens or similar enclosed di s d p tain par cul ly to a shif able rack structure adapted to be connected with the door of the oven and to he moved outwardly therefrom when the door is opened and replaced therein when the door is closed.

The primary object ofthe present inven- 0 tion, in addition to the provision of a rack or racks shiftable with and by the door of the body in which they are mounted, is to provide an improved type of shiftable frame ich i dapt to arry a pa r ofrf cks, on

thereof being completely removable from the frame so that the other may be used alone in the oven when the maximum capacity of the oven is to be made use of,

Another object of the invention is to prov a ra ay upp rting frame of unique design, it being so COIl$tructed that side members thereof may act as runners in guide grooves or tracks, while a rear portion thereof which is disposed 1113 .1 Offset plane with respect to the side port1ons,may

be employed for supporting one side of the oven rack.

Other objects and advantages of the present invention Will become apparent as the m description of the same proceeds and the in vention will be best understood from a consideration of the following detailed description taken in connection with the accompany a ing drawings forming part of the present invention with the understanding,however that the invention is not confined to any strict conformity with the showing. of the drawings but maybe changed or modified .40 so long as such changes or modifications mark no material dep arturefrom the salient features of the invention as expressed in the ap ended claims.

n the drawings i l 5 Figure 1 is a vertical sectional view through an oven showing the door thereof open and the racks is drawn out position.

Figure 1 showing the door closed 7 and vthe racks within thev oven.

Figure 3 is a sectionalview taken substantially upon the line 33 of Figure 2.

Figure 4 is a. horizontal sectional View through one side of the closed'oven looking down upon the racks.

Referring more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates gen erally an ordinary type of' stove or range body showing therein the casing 2 which constitutes the oven. The front'or open part of the oven may be closed by the use of the door 3 which is hingedly attached to the bottom edge thereof in the usual manner, as in i a d a 4 i ecure hor zont lly to t nn r fac o each of the side walls 5 are the upper and lower track members 6 and 7 respectively,

' which as shown in Figure 3. are formed inte-v gral with a plate 9, the upper edge of which has formed intermediate the ends thereof the ear 10 through which a set screw 11 is passed into the adjacent wall of the oven to maintain the plate in position while the lower edge ha adjacent it nne n a h ok 12 wh ch is engaged over one of a pairrof pins 13 on the adjacent wall, and a notched'lug 1&1 adjacent, the outer end which is engaged over the other pin-projecting from the adjacent wall. 7 1

Adjacent the. inner end of each upper track 6' there is formed upon the upper face thereof a caml Slldflble into the, ,OVGH with its sides in the eces formedbe ween the spaced track members 6 and, 7 at the sides thereof, is a frame that isindicated as a whole by the numeral 16. This frame in planv viewpresenjts a substantially U-shaped outline, each side bar V orleg 17 thereof being arranged with its outer edge slidably' positioned between a pair of track 6 an .7 assl rovvu.v Th icros bar 18 which connects theinner ends of the bars or legs, 17 is "arranged in a lower plane than t the sidebars andis connected thereto through.

V v. the medi m he m mbers 19 whieh,.when Figure 2 1 a se t onal view similar to the frame is n p sition, d pend, from h sideb rs. 17 in th m nner sho n- A flieir portions 20 set inwardly as shown in Figure 4.

Adjacent the rear of the slidable frame 16 each bar or leg 17 thereof carries an upstanding ear 21 which as shown in Figure 3 is spaced from the adjacent wall of the oven and carries an outwardly projecting pin 22.

The pin 22 of each ear 21 isslidably positioned in an elongated slot 23 formed through the inner end of a pull bar 24, the inner end of this slot 23 having an upwardly directed offset 25 which receives the pin 22 at one period in the operation of the device, as will be hereinafter described, the pin at certain periods riding from one end of the slot 23 to the other so astopermit an idling 'movement of the pull bar 24 Without shifting the trays carried the frame 16.

'2 At their outer ends each of the pull bars 2 24 has pivotal connection, as'at 26, with one s end of an arm 27 ,which is securedrigidly to the adjacent inner face of thedoor 3 at an angle thereto, as shown.

. .From the descriptive matter thus far given 5 it will be readily seen that when the door ceptacle is to be placed therein on the lower firacle I V avard edge of the lower rack sets in a considerable distance beyond the forward edge of 11; win as be head thaaeiowa rack 30 is materially shorter than the upper rack 38 and while the rear edges thereof are in substantially the-same vertical plane the for V the upper rack so that it will not come'into contact with the door when the latter is swung open and the frame is drawn outward- .ly thereby. It'will alsobe seen that when the door is first opened it will have short -3 is .in closed position the bars 24 will be shoved in to the point where each pin 22 will be positionedin the forward end of a ride thereon and thus raise the bars free from the pins, permitting movement of the bars the length of the slots 23 without affecting the frame 16. p

At the forward end of is suspended a cross bar 28 which at its ends has the upwardly directed arms 29 for connection with the side members'7 thereof.

Having thus described our invention, what f we claim is advancingrear ends of the bars they will '1.
